Acquisition and reversal in the Morris water maze task for seven inbred mouse strains. Mice were given up to nine days to reach criterion for learning, set at a group average latency of 15 seconds or less to find the hidden platform. After reaching criterion on the original acquisition, the location of the hidden platform was changed to a new quadrant for the reversal task. Data shown are mean (± SEM) of four trials per day.
